Remotely controlled oil drain valve

Abstract

A remotely controlled oil drain valve device to be installed in the threaded drain plug opening of automotive crankcase permitting drainage of crankcase oil without removal of the crankcase plug. A cylindrical tapered valve core having cylindrical arms extending from end surfaces of said cylindrical tapered valve core and being seated in a cylindrical tapered valve seat opening of a cylindrical valve body having an affixed threaded tubular nipple extending radially from said cylindrical valve body, and a disk-shaped cable bracket yoke having an extended arm affixed selectively to said cylindrical valve body by means of threaded fasteners. A cable control arm affixed radially to said cylindrical tapered valve core which, when activated by a remotely located cable control mechanism affixed to a mounting bracket, initiates rotational movement of said cylindrical tapered valve core simultaneously overcoming the action of the return spring, thereby facilitating the registration of the diametrical openings in said cylindrical valve body with the diametrical opening of said cylindrical tapered valve core effecting the drainage of oil from said automotive crankcase.
